[u][b]QSC USA 850 - 850 watt power amplifier[/b][/u] - £79 only
This is the series of amplifiers that originally made QSC's worldwide reputation. Beautifully built (in the USA), they were made to go on forever, are ultra-reliable but fixable should the need arise. This one is 3u high and very compact (fits in a shallow 19" case), which makes it much easier to pick up and carry than an amp of standard depth. Brief specs as follows:
Output
4 ohms 425 watts per channel
8 ohms 255 watts per channel
Bridgeable into 8 ohms
Frequency Response: 20Hz to 20kHz, +0/-1dB, 1 watt
Damping Factor: Greater than 200
Noise: 104dB below rated output (A weighted)
Cooling: Two-speed fan, rear-to-front air flow.
Load Protection: On/off muting. DC-fault protection
Weight: 15kg
Dimensions: Standard 19" rack mounting faceplate
Height: 5.25"(13.3cm).
Chassis Depth: 9.5" (24.1cm)
These are being used quite a bit for home hi-fi and theatre (thanks to a very quiet fan), especially in the US, where used prices seem to be higher than here. Pickup welcome, or delivery at cost.
